PU 2.1: Physical Unit type 2.1
Physical Unit type 2.1 (PU 2.1) is an SNA network node used for connecting peer nodes in a peer-oriented network. PU 2.1 sessions do not require that one node reside on VTAM. APPN is based upon PU 2.1 nodes, which also can be connected to a traditional hierarchical SNA network.
